STw5210

24-bit, 103 dB SNR audio DAC with playback time extender

Data Brief

Features

■ DAC

– 24-bit audio DAC

– 103 dB dynamic range for the full audio

path

VQFPN-44

7x7x1mm

0.5mm pitch

TFBGA-40

4x4x1.2mm

WLCSP-36

2.6x2.6x0.6mm

0.4mm pitch

– THD -66 dB (0.0 5%) on 32 Ω

– Sampling rate: 8 kHz to 48 kHz

■ Analog output drivers

– Operating mode selection: PTE™playback

time extender or standard (continuous)

mode

– Stereo headset amplifier

- ‘True ground’ output amplifier

(no coupling capacitor).

- 2x50 mW on 32 Ωand 2x80 mW on 16 Ω

- 66 dB programmable gain

- Plug detection, click/pop suppression,

independent right and left channel

shutdown control

– SNR and consumption adjustable by

■ Supply

– Direct connection to the battery

(2.7 V to 4.8 V) thanks to integrated power

management

– Stereo differential line out

– I/O supply: 1.62 V to 3.6 V

■ RoHS (lead-free) packages

■ Power consumption

– Stand-by: 1 µW

Description

– Playback: 44 mW for 103 dB SNR,

29 mW for 94 dB SNR

The STw5210 is a 24-bit high performance DAC

for mobile handset application with 103 dB

dynamic range for the whole audio path.

■ PTE™ function

– Integrated programmable PTE™ memory to

store up to 100 ms of music

It embeds an innovative PTE™ function that

reduces drastically the whole application power

consumption. In this mode, the music is played

back autonomously, while the whole system is

switched to power saving condition. The IC is then

driven by the 32 kHz clock only. The device can

be used also in a conventional way (continuous

mode) and be driven by the system clock.

STw5210 is very easy to integrate and thanks to

its embedded power management, it can be

directly connected to the battery.

(5120 x 24-bit stereo words).

– ^{Empty PTE}™ memory detection pin

– Auto-reset interrupt

■ Inputs

– I²S digital input up to 50 MHz

(in PTE™mode)

– Stereo single ended or differential analog

input

■ Clock

The device foot print is very small as the EBOM is

reduced to a few components. The 50 mW

headset amplifier is of “True-ground” type (no

coupling capacitor) and no additional quartz is

required in PTE™ mode, when the PLL is driven

by the 32 kHz frequency.

– 32 kHz only needed in PTE™ mode

– System clock input (13 MHz, 19.2 MHz,

26 MHz and 38.4 MHz) for standard

(continuous) mode

– Internal PLL
